Title: Improvements in the production of ferro-cobalt
IPC: C25C1/24
Filed: 1933-06-22
Abstract: 416,158. Electrodeposition of ferro - cobalt. BOSQUI, F. L., N'Kana, Northern Rhodesia, and RHOKANA CORPORATION, Ltd., 13, Austin Friars, London. June 22, 1933, No. 17792. Drawings to Specification. [Class 41.] A commercially pure alloy of iron and cobalt is obtained electrolytically from suitable copper slags, by employing as anode an alloy or mixture containing not more than 15 per cent of copper, and an electrolyte containing less than three grams of free acid, reckoned as sulphuric, per litre (preferably 1-2), and'a copper content which does not exceed 0À05 grams per litre. The ferro-cobalt is deposited on the cathode and the bulk of the copper is deposited in the cell as sludge. The copper content of the electrolyte may be controlled by withdrawing a portion of it, preferably continuously, removing the copper, e.g. by cementation on scrap iron or cobalt, and returning it to the cell. In the case of mixtures containing more than 15 per cent of copper, the process may be repeated, using the cathode deposit of one stage as the anode of the next.

Title: Electrophilic substitution of nitrosamines
IPC: C07D211/98
Filed: 1973-04-13
Abstract: 1417338 Electrophilic substitution of nitrosamines BADISCHE ANILIN- & SODAFABRIK AG 13 April 1973 [15 April 1972 22 Sept 1972] 17818/73 Heading C2C Electrophilic substitution of a nitrosamine on the carbon atom α to the amino nitrogen is achieved by metallizing in the α position the nitrosamine of a secondary amine which bears at least one hydrogen atom in this position, and reacting the metallized product with an electrophite. In the nitrosamine R 1 R 2 N.NO, R 1  and R 2  may for example be alkyl, cyclohexyl, phenyl or benzyl, or the amino nitrogen may be part of a heterocyclic ring. The metallizing metal may be an alkali or alkaline earth metal or zinc, cadmium or monovalent copper, and organometallic compounds may be used as metallizing agent; lithium diisopropylamide is the preferred agent. Suitable electrophiles include carbonyl compounds, alkylating agents, e.g. alkyl or substituted alkyl halides, sulphates and sulphonates, acylating agent (carboxylic acid chlorides, esters, anhydrides, alkali metal salts, amides, nitriles, isocyanates, ketene and carbon dioxide); halohydrins obtained when using haloketones may react further by elimination of hydrogen halide to give epoxide; when using acyl halide, the resultant carbonyl compound may react with a further nitrosamine compound (e.g. PhCOCl with (CH 3 ) 2 N.NO gives PhCOR and/or PhC(OH)(R) 2  where R is CH 3 N(NO)CH 2 -). Inorganic electrophiles may also be used; use of iodine results in oxidative coupling of two nitrosamine molecules (e.g. RN(NO)CH 3  gives (RN(NO)CH 2 -) 2  where R is alkyl or aryl). Products may be reduced to hydrazines, or denitrosated to amines; products obtained when using carbonyl compounds contain hydroxy groups and may be dehydrated (e.g. benzaldehyde + dimethyl nitrosamine # PhCH(OH)- CH 2 N(NO)CH 3  # PhCH=CH-N(NO)CH 3 ).

Title: Luminous electric discharge tube
IPC: H01J61/54
Filed: 1931-06-20
Abstract: 389,512. Discharge apparatus. RAINBOW LIGHT, Inc., 21, 44th Road, Long Island City, New York, U.S.A.-(Assignees of Machlett, R. R. ; 25, Dorchester Road, Scarsdale, New York, U.S.A.) June 20, 1931, No. 17906. Convention date, June 26, 1930. [Class 39 (i).] A discharge lamp which can also be used as. a rectifier, oscillator, amplifier, &c. has two alternative paths for the discharge, one path having a low starting potential and a rising voltage characteristic. the other having a high starting potential and a falling voltage characteristic. The lamp can thus be started on a low voltage supply, the initial current flowing along the former path. The lamp is so constructed that the transference of the current from the first path to the second takes place automatically. In the lamp shown in the Figure the electrodes 11 are situated at the ends of the tube 10, the path between the electrodes constituting the path of high starting potential. A conductor 14 is arranged along the axis of the tube but is insulated from both electrodes by supports 15, the conductor and the gaps G between its ends and the electrodes forming the path of low potential. When current is supplied to the lamp the discharge first passes through the gaps G and along the conductor 14. The voltage characteristic of this path rises until the discharge finally takes the path between the electrodes 11. The tube contains neon, argon, mercury vapour &c. and the conductor 14 is in the form of a fine wire of iron or other material that does not sputter readily. A shield may be mounted between the conductor 14 and the wall of the tube to prevent sputtered material from being deposited on the tube, openings being provided in the shield for the passage of ions. In long tubes the single conductor 14 may be replaced by a number of conductors placed end to end with gaps between. The tube when used as a lamp may be used in the electrical transmission of pictures and the photographic recording of sound.

Title: Production of cellular synthetic rubbers
Inventor: MERRIMAN PETER
IPC: C08J9/30
Filed: 1954-06-21
Abstract: Polyurethane foams are prepared by dispersing an inert gas under pressure into a liquid intermediate reaction product of a polyisocyanate and a polyester, polyether or polyesteramide, the intermediate containing free isocyanate groups, releasing the pressure to cause the intermediate to expand and curing the expanded material.  Expansion may be enhanced by the presence of water, carboxylic acids, hydrogen peroxide, organic peroxides and hydroperoxides, if necessary with additional polyisocyanate, volatile liquids or liquefied gases.  The composition may include accelerators, plasticizers, thickeners, surface active agents and cross-linking agents (polyhydric alcohols, water, polyamines, amino-alcohols) which may have been reacted with the intermediate product.  Pressures up to 1000 p.s.i. are referred to, the intermediate with any additions and containing the dispersed gas being passed through a continuous pressure reactor, which may be a scraped surface heat exchanger, leaving the reactor by a pressure reducing valve and being discharged into moulds or on to a conveyer belt.  In an example 15 per cent by weight of aluminium naphthenate was mixed with a polyglycol adipate and then successively 4 per cent of a mixture of tertiary amines, 2 per cent of triethylamine and 12 per cent of mixed toluene diisocyanates were mixed in and the whole fed to a scraped surface reactor at 2 DEG  C. together with sufficient carbon dioxide from a cylinder of liquid carbon dioxide to give a final product of density 0.05 grams/cc.  The pressure in the reactor was 350 p.s.i. The emerging foam was directed into moulds, left for 20 minutes to set at room temperature and matured at 50 DEG C. in a hot air oven.  The foam was mangled, trimmed and sliced.

Title: Improvements in or relating to electronic switching circuits
IPC: H03K23/82
Filed: 1949-07-08
Abstract: 686,986. Digital electric calculating-apparatus. BRITISH TABULATING MACHINE CO., Ltd. July 8, 1949 [July 9, 1948], No. 18103/49. Class 106 (i). [Also in Group XL(c)] An electronic commutator (i.e. a series of chain-connected circuits, each having two conditions of stability, so arranged that applied pulses cause each circuit in turn to assume a chosen stable condition) comprises two-valve trigger circuits connected by grid-controlled coupling valves to which pulses are applied simultaneously, and means for placing one trigger in a chosen stable condition to render the commutator responsive to the pulses. The commutator may be used to control the selective generation of pulse wave-forms in the calculating apparatus of Specification 673,759. As shown, four trigger circuits A, B, C, D are coupled by circuits H, I, J, K to form a ring- type commutator to which positive pulses are applied from a terminal 76 through a shaping circuit S. Each pulse is applied to the grid of amplifier 26, and a resultant negative pulse at the anode is passed through a differentiating circuit 33, 35 to the control grid of valve 27. The valve current is thus reduced and a positive pulse is sent via lead 74 and capacitors 75 to the grid circuits of coupling valves 37, 45, 52, 59. At the start of operations switch CBS is opened to cancel the bias on the grids of trigger valves A1, B2, C2, D2, which are thus rendered conductive (as shown by dots). The fact that A2 is not conducting, due to connection 38, will cause the grid of valve 37 to be initially at a higher potential than the grids of the other coupling valves. Thus the first pulse received renders only valve 37 conductive so that a negative pulse is sent over lead 44 to switch over trigger B. Valve B1 then conducts and a negative pulse is sent from its anode circuit through lead 66 and capacitor 67 to the grid of valve A1 to switch over trigger A. A capacitative connection 66a is provided also from supply line 13 to the grid of valve A2 so that any disturbance on the line is sent equally to both valves of the trigger. When B1 conducts the higher potential is applied to coupling valve 45 so that the next received pulse simi. larly switches over trigger C and returns trigger B to the condition shown. The next pulse switches over trigger D and returns trigger C, trigger A following trigger D, and so on indefinitely. In a modification, a negative pulse must be applied to trigger A before the commutator is responsive to pulses from the shaping circuit, the commutator then passing through a single cycle of operations only, and the commutator is reset, automatically by a switching circuit associated with the last trigger, or by connecting this trigger to an external pulse source.
